Pfacoemulsification is a surgical method of cataract removal introduced by the American Charles Kelman in the 1960s; it is a modified version of extracapsular cataract extraction through a small incision. The technique of phacoemulsification consists of several steps. The ultimate goal of the surgery is less intervention and better visual results.
Incision - small sclerocorneal and corneal incisions that does not require sutures to close are made enabling exquisite control of the operation by the surgeon.
Capsulorrhexis - the anterior surface of the lens capsule is removed. This delicate manoeuvre is necessary for mobilisation and emulsification of the lens nucleus.
Hydrodissection and hydrodelineation - endocapsular phacoemulsification provides effectiveness, accuracy and safety. It is made within the capsular bag to avoid damage to the corneal endothelium and the posterior lens capsule.
Surface cortex aspiration - Hydrodissection and hydrodelineation make it possible to leave as little residual cortex as possible after the nucleus is removed. Nowadays there are many special instrumentations that facilitate this stage of operation.
Insertion of the IOL - the patient can choose between a rigid IOL or IOLs made from flexible, UV-absorbing plastics such as silicones or acrylics. The lens is inserted into the capsular bag.
